Actually with the warmer months comes fleas and flies the intermediate host for our next guest, TAPEWORMS! I probably get more phone calls about this parasite then any other parasite. OMG there are these little white things on my animals rectum or on their stool (about 1/4 to 1/3 inch long) and they are moving!!! Usually right after they defecate. Can I catch them and they are so GROSS. Now the good news, no you probably will not catch them, you need to eat an infected flea or fly to complete the life cycle and they are relatively benign i.e. they probably will not make your animal sick. The perfect parasite able to peacefully coexist with their host without making them sick. Easy to treat too, either a shot or oral pills, two treatments two weeks apart.
